Product Information
PT Tri-Die Silica + Pyrethrin Dust Insecticide
PT Tri-Die Dust is a professional-grade, ready-to-use insecticide dust that delivers both immediate knockdown and long-lasting residual control.
This dual-action formula combines botanical pyrethrins for quick kill with amorphous silica that continues working for weeks by damaging insects’ protective outer layers.
Designed for crack-and-crevice, void, and harborage treatments, Tri-Die is ideal for hard-to-reach areas where sprays cannot be applied safely or effectively.
It is widely used in residential, commercial, and sensitive environments such as food-handling facilities when applied according to label directions.
Why Use PT Tri-Die Dust
Dual mode of action: Pyrethrins provide fast knockdown while silica delivers long-term residual control.
Excellent for hidden pests: Penetrates cracks, voids, wall cavities, and other harborage areas.
Dry application: Ideal where liquids are not appropriate.
Broad-spectrum control: Targets crawling insects, stored-product pests, and occasional invaders.
Pro-grade performance: Built for structural pest control in homes and commercial settings.
When to Use
At the first signs of pest activity
During seasonal invasions (ants, spiders, cluster flies, clover mites, etc.)
When pests are hiding in wall voids, cracks, and other hard-to-reach harborage areas
As part of an IPM program alongside exclusion and sanitation
Retreatment
Reapply as needed when new activity is observed or treated dust is removed/covered.
Residual control lasts as long as the dust remains dry and undisturbed.
Do not apply more than 1 time per day.
Pro Tips
Less is more—apply a fine, barely visible layer to avoid repellency and clumping.
Target entry points and pathways (door frames, plumbing penetrations, under sinks, behind appliances).
Keep applications dry; avoid applying outdoors during rain and avoid watering to runoff.
